[0001] The present invention relates to a digital broadcasting receiving device with an advertising information outputting function capable of receiving digital broadcasting and presenting advertising information to a user.
[0002] A digital broadcasting receiving device for receiving digital broadcasting using a satellite or a ground wave selects an arbitrary broadcasting wave out of a plurality of broadcasting waves which are received through a dedicated antenna or a ground wave antenna by a tuner, selects an arbitrary channel out of a plurality of channels included in the selected broadcasting wave by demultiplexing processing, takes out a digital signal on the selected channel, and decodes the digital signal, to output a video/audio signal.
[0003] Meanwhile, a commercial (CM) in conventional television broadcasting is in a mass communication manner in which the same commercial is presented to all viewers. Partially in a local broadcasting station, a commercial in the local edition is only inserted. That is, it is not realized that a local commercial closely related to a living area of the viewer is continuously presented. Further, even if a time service or the like is unexpectedly furnished in a shop existing in the vicinity of a residential area of the viewer, it is not realized that the viewer is timely informed that the time service is furnished through television broadcasting.
[0004] The present invention has been made in view of the above-mentioned circumstances and has for its object to provide a digital broadcasting receiving device with an advertising information outputting function capable of presenting, in a place where a viewer is currently positioned, local commercials corresponding to the place.
[0005] In order to solve the above-mentioned problem, a digital broadcasting receiving device with an advertising information outputting function according to the present invention is characterized by comprising a receiver for receiving a digital broadcasting wave; video/audio output means for outputting at least one of video and audio; means for taking out advertising information and advertising area information which are carried on the digital broadcasting wave; means for outputting information related to the current position; selection means for selecting the advertising information by the contrast between the information related to the current position and the advertising area information; and a controller for feeding the selected advertising information to the video/audio output means at predetermined timing.
[0006] In the above-mentioned configuration, the receiving device is fixedly installed in each home or the like, and the information related to the current position is inputted to the device by a user, for example. On the side of a broadcasting enterpriser, transmission is made with the advertising information and the advertising area information corresponding thereto carried on the digital broadcasting wave. In an advertisement for a shop which exists in New York, for example, the advertisement is transmitted with advertising area information representing “New York” added thereto. The device selects the advertising information by the contrast between the information related to the current position and the advertising area information, and outputs the selected advertising information by video/audio. In a place where a viewer is currently positioned, therefore, local commercials corresponding to the place are presented.
[0007] A digital broadcasting receiving device with an advertising information outputting function according to the present invention is characterized by comprising a first receiver for receiving a digital broadcasting wave; video/audio output means for outputting at least one of video and audio; means for taking out advertising information and advertising area information which are carried on the digital broadcasting wave; a second receiver for receiving a transmission wave on which information required to specify the current position is carried; means for outputting information related to the current position on the basis of the information carried on the transmission wave; selection means for selecting the advertising information by the contrast between the information related to the current position and the advertising area information; and a controller for feeding the selected advertising information to the video/audio output means at predetermined timing.
[0008] In the above-mentioned configuration, the information related to the current position is acquired on the basis of a transmission wave from satellites in a GPS (Global Positioning System) or a beacon transmitter provided in a street corner, for example. On the side of a broadcasting enterpriser, transmission is made with the advertising information and the advertising area information corresponding thereto carried on the digital broadcasting wave. In an advertisement for a shop which exists in ◯◯ town, for example, the advertisement is transmitted with advertising area information representing “◯◯ town” added thereto. The receiving device selects the advertising information by the contrast between the advertising area information and the information related to the current position which is acquired by the second receiver, and outputs the selected advertising information by video/audio. Even in a case where the receiving device is moved with the device carried in a vehicle such as a bus, a family car, or a railroad car, or a case where the receiving device, together with a user, is moved as a portable device, therefore, local commercials corresponding to a place to which the device is moved are presented in the place.
[0009] The device may comprise a memory storing the advertising information and the advertising area information which are taken out of the digital broadcasting wave, and the selection means may be constructed such that the advertising information stored in the memory can be selected by the contrast between the information related to the current position and the advertising area information. This makes it possible to previously acquire and store advertising information collectively broadcast at midnight, for example, and output, even if no advertising information is broadcast in the daytime, the stored advertising information by video/audio.
[0010] A digital broadcasting receiving device with an advertising information outputting function according to the present invention is characterized by comprising a first receiver for receiving a digital broadcasting wave; video/audio output means for outputting at least one of video and audio; a memory storing advertising information and advertising area information; a second receiver for receiving a transmission wave on which information required to specify the current position is carried; means for outputting information related to the current position on the basis of the information carried on the transmission wave; selection means for selecting the advertising information by the contrast between the information related to the current position and the advertising area information; and a controller for feeding the selected advertising information to the video/audio output means at predetermined timing.
[0011] In the above-mentioned configuration, the information related to the current position is acquired on the basis of a transmission wave from satellites in a GPS or a beacon transmitter provided in a street corner, for example. The advertising information and the advertising area information corresponding thereto are stored in the memory. In an advertisement for a shop which exists in ◯◯ town, for example, the advertisement is stored with a correspondence between the advertisement and advertising area information representing “◯◯ town” established therebetween. The receiving device selects the advertising information by the contrast between the advertising area information and the information related to the current position which is acquired by the second receiver, and outputs the selected advertising information by video/audio. In a case where the receiving device is moved with the device carried in a vehicle such as a bus, a family car, or a railroad car, or a case where the receiving device, together with a user, is moved as a portable device, therefore, local commercials corresponding to a place to which the device is moved are presented in the place.
[0012] The device may comprise judgment means for judging whether or not video and audio which are being currently outputted are a commercial (CM) appended to a program, and the controller may be so constructed as to feed to the video/audio output means the advertising information selected when the judgment means judges that they are the commercial (CM). This makes it possible to provide the advertising information in place of the commercial appended to the program without affecting the program itself.
[0013] The controller may be so constructed as to feed the advertising information selected in the selection means to the video/audio output means simultaneously with the selection. This makes it possible to avoid such situations that the receiving device separates, if it waits for certain timing, from an advertising area because it is moving, and misses the chance to present the advertising information and to reliably present the advertising information to the viewer.
[0014] When a signal representing the timing of outputting the advertising information is received, the controller may feed the advertising information selected in the selection means to the video/audio output means. Examples of the signal representing the output timing include an output instruction signal carried on the digital broadcasting wave. Further, when a beacon is transmitted only when required, a beacon signal also becomes a signal representing output timing.
[0015] The device may comprise message output means for outputting a message saying that the advertising information exists, and the controller may be so constructed as to feed the advertising information selected when an advertising output operation is performed by a user to the video/audio output means. Consequently, the advertising information is outputted by video/audio on the basis of the intension of the user.
[0016] The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the appended to drawings.
[0017]
[0018]
[0019]
[0020] An embodiment of the present invention will be described on the basis of
[0021] In
[0022] A tuner
[0023] A demultiplexer (DEMUX)
[0024] The demultiplexer
[0025] As described in the foregoing, a plurality of channels are multiplexed on the transport stream. Processing for selecting any one of the channels can be performed by taking out data indicating which packet ID in the transport stream is used to multiplex the arbitrary channel from the PSI/SI.
[0026] Not only a main channel but also a subchannel is multiplexed on the digital broadcasting wave. When a DEMUX control signal is fed to the demultiplexer
[0027] Furthermore, data broadcasting for providing a still image, character information, and audio information is also multiplexed on the digital broadcasting wave. In program broadcasting, a commercial (CM) is inserted everywhere. However, advertising information other than the commercial can be incorporated into the subchannel or the data broadcasting. Of course, a channel that specializes in advertising information can be also provided.
[0028] Information indicating in which subchannel, for example, the advertising information exists, and advertising area information (e.g., information related to latitude and longitude) indicating in which area the advertising information should be broadcast are previously inserted into the SI. On the side of the transmission of the advertising information (on the side of a broadcasting enterpriser), even if a system capable of not only successively sending out advertising information previously requested but also coping with an unexpected advertising request is arranged, it is possible to timely carry, when a certain shop unexpectedly furnishes a time service or the like, advertising information for informing a viewer that the time service is furnished on the broadcasting wave.
[0029] The AV decoder
[0030] The video data generated by the decoding is outputted to a video processing circuit
[0031] The video processing circuit
[0032] A GPS (Global Positioning System) receiving circuit
[0033] A beacon receiving circuit
[0034] The CPU
[0035] The CPU
[0036] When the above-mentioned digital broadcasting receiving device with an advertising information outputting function is moved with the device carried in a vehicle such as a bus, a family car, or a railroad car, the information related to the current position is gradually changed. Accordingly, in a place where a viewer is currently positioned, local advertising information corresponding to the place is presented.
[0037] It is also possible to perform processing for selecting advertising information which is being currently broadcast on the basis of the information related to the current position when a program which is being currently broadcast is switched into a commercial, to output the advertising information without comprising the CM data memory
[0038] It is possible to take the time when a pilot signal (an output instruction signal) multiplexed on a digital broadcasting wave is received as timing of outputting advertising information besides taking the time when a program is switched into a commercial as timing of outputting advertising information. Alternatively, if a beacon is transmitted only when required (for example, transmitted when a time service is started), a beacon signal also becomes a signal representing output timing.
[0039] Although description was made of a case where the advertising information is carried on the subchannel, the present invention is not limited to the same. For example, the advertising information may be carried on sub-audio on a main channel or on data broadcasting multiplexed on a digital broadcasting wave as additional information to take out the advertising information. In the configuration comprising the CM data memory
[0040] There may be provided a shop data memory
[0041] Although the configuration comprising both the GPS receiving circuit
[0042] Furthermore, in the configuration shown in
[0043]
[0044] The OSD circuit
[0045] The speech synthesis circuit
[0046] The remote control transmitter
[0047] Also in the configuration shown in
[0048] Specifically, when advertising information corresponding to an area exists in a digital broadcasting wave, the CPU
[0049] When the user operates the remote control transmitter
[0050] The message to be displayed is not limited to the character message. For example, a predetermined mark may be intermittently displayed in a corner or the like of the screen. Further, light emission means such as an LED (Light Emitting Diode) may be flashed without using the OSD circuit
[0051] Although in the configurations shown in
[0052]
[0053] The current position memory
[0054] When advertising area information carried on a digital broadcasting wave is the names of a city, a town, and a village, a postal code, or the like, the information related to the current position which is the names of a city, a town and a village, a postal code, or the like can be fed to the CPU
[0055] The CPU
[0056] Although description was made as an example of a case where ground wave digital broadcasting is viewed, the present invention is not limited to the same. It can be also applied to a case where BS digital broadcasting or the like is viewed.
[0057] As described in the foregoing, according to the digital broadcasting receiving device with an advertising information outputting function in the present invention, such an effect that in a place where a viewer is currently positioned, local commercials corresponding to the place can be presented to the viewer by the digital broadcasting wave or on the basis of the advertising information previously stored.
[0058] Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
